How to enter DFU mode on iPhone 15

In some rare cases, you may need to place your iPhone 15 into Device Firmware Upgrade (DFU) mode to reinstall iOS. Like recovery mode, you’ll need to connect your iPhone 15 to a computer using a USB-C to USB-C cable. If this is the first time connecting your iPhone toyour Mac, you’ll need to go through the trust process explained in the recovery mode section above to establish a pairing with your Mac.

To enter DFU mode, do the following steps in quick succession:

Step 1: Quick-press Volume up and release.

Step 2: Quick-press Volume down and release.

Step 3: Long-press the Side button for 10 seconds.

Step 4: While long-pressing the Side button, long-press the Volume down button for 5 seconds.

Step 5: Release the Side button while continuing to long-press the Volume down button for an additional 10 seconds.

Unlike recovery mode, no connect-to-computer dialogue is displayed when entering DFU mode. After entering DFU mode, your iPhone 15 display will remain black. If the Apple logo appears, the process was not performed correctly.
